"They're going right to the rack," Staudt said. "We sold one this morning before we even opened."

President Barack Obama and federal lawmakers have reignited the debate for stricter gun regulations. Homeland Security Secretary Jeh Johnson has said that gun control is now "part and parcel of homeland security."

Staudt, a former U.S. Marine, said this kind of talk about gun control typically leads to more people purchasing guns that would not have normally bought guns. However, the current discussions haven't led to a surge in gun purchases.

"It's not at a panic level yet," Staudt said.

"[The fear of the government taking guns away] has been somewhat overblown in the past, but you never know. And people don't want to take the chance."

Lamb said gun sales can swing wildly depending on the economy and what's going on in the world. At times, guns are luxury items that are only purchased by enthusiasts. At other times, like after a mass shooting, people see guns as a necessity.

After the Sandy Hook Elementary School shooting in 2012, lawmakers from all over the country proposed new gun regulations or worked to reinstate the federal assault weapons ban.

Lamb said that's when wives tell their husbands to pick up the essentials, "milk, bread, eggs and remember to buy an AR-15 and a bunch of ammo."

"It becomes a necessity in their mind," Lamb said. "They think to themselves, 'I have to buy one.'"

Staudt said the regulations following the Sandy Hook shooting led to the "biggest spike in sales we'd ever seen before."

"A standard AR-15 that sells for $700, were selling for $2,500," Staudt said. "You ran out of everything."

Sales also rose after the San Bernardino shooting and the attacks in Paris in 2015, he said.

Lamb said the proposed gun regulations after the Sandy Hook shooting had a "massive" effect on gun sales. Since there has not been as much talk about gun control following the Orlando shooting, Lamb said the sales increase has been slight.

"It's human nature, maybe it's American nature, but I think it's human nature," he said. "If anything is threatened to be taken away, people run out and buy it"
